When I try to download your file, I get an "Invalid Attachment specified"
message from excelforum. Besides it is usually more informative if you can
answer the following few questions about your situation.
What is in A2 and what is in a cell that should match.
What is the result of ISNUMBER() for A2 and the supposedly matching cell?
If the cells contain formulas, trace back the contents of referenced cells
until you get to actual inputs. Alternately if the cells contain numbers,
give the results of D2B() or D2D() for A2 and the supposedly matching cell,
where the VBA code for these functions is given at
